Element for coupling a lighting appliance to an electric rail

Abstract

An element for coupling a lighting appliance to an electrified rail includes two separate components, the first of which exclusively provides the electrical connection to the electrified rail, and the second of which is mechanically separate from the first component and is of essentially of box form. In one embodiment, the second component includes a U-shaped bracket configured to clamp to the electrified rail from the outside, to support the lighting appliance, and to house electrical components, each lateral flange of the clamping bracket having an inner surface that is partially shaped to be complementary to the outer surface of the rail. The second component further includes a U-shaped bracket configured to interlink with the clamping bracket and to confine the volume defined by the clamping bracket that is not taken by the rail.

1. An element for coupling a lighting appliance to an electrified rail comprising:
 a first component configured to provide only an electrical connection to the electrified rail; and 
 a second components, mechanically separate from the first component and of essentially box form, comprising,
 a U-shaped clamping bracket configured to clamp to the electrified rail from outside of the electrified rail, to support the lighting appliance, and to house one or more electrical components, the clamping bracket comprising lateral flanges each having an inner surface, at least a portion of which is shaped complementary to an outer surface of the rail, and 
 a U-shaped closure bracket configured to interlink with the clamping bracket to confine a volume, which is defined by the clamping bracket and which is not occupied by the electrified rail. 
 
 
     
     
       2. The element of  claim 1 , wherein the inner surfaces of the lateral flanges of the clamping bracket are at least partially shaped to conform to outer surfaces of different electrified rails. 
     
     
       3. The element of  claim 1 , wherein each of the inner surfaces of the lateral flanges of the clamping bracket includes two distinct zones configured to couple with lateral areas of two different electrified rails. 
     
     
       4. The element of  claim 1 , further comprising one or more fasteners for engaging at least one of the lateral flanges of the clamping bracket such to affix the at least one of the lateral flanges to the electrified rail. 
     
     
       5. The element of  claim 1 , wherein the closure bracket and the clamping bracket are mechanically connected with one or more screws passing through one or more openings provided in at least one of the lateral flanges of the closure bracket and engaging one or more internal longitudinal slots provided in the clamping bracket. 
     
     
       6. The element of  claim 1 , further comprising a member supporting the lighting appliance, the member being coupled to a lateral flange of the closure bracket. 
     
     
       7. The element of  claim 6 , wherein a plurality of openings are provided in the lateral flange of the closure bracket where the member is coupled, the plurality of openings being configured for passage of electric cables connecting the one or more electrical components, housed within a space delimited by the clamping and closure brackets, to the first component and to the lighting appliance.
